Water Properly

Improperwatering of tomato plantsis one of the leading preventable causes of blossom end rot.

Excessively dry or waterlogged conditions and extreme fluctuations in moisture affect the plants ability to absorb calcium.

Keeping the soil evenly moist but not soggy can reduce the chances of problems developing.
